APOD 4.2

Oops! Messier Moment! In this photograph taken in a field adjacent to Tänndalen, Sweden, the comet PanSTARRS soars through the northern skies, brightness rivaling that of M31, the Andromeda Galaxy. Thus the two are both seen bright in the sky, along with the double cluster h and chi Persei along the Milky Way, which can be used as a guide to the aplha star of Cygnus, Deneb.
